Design a natural gas power engine which can provide 1MW power output. In the design, you have to provide us the pressure ratio, inlet/outlet diameters of the compressor and turbine in the final answer. The required stoichiometric air-fuel ratio and heating value of natural gas can be found through google searches. Your power engine should be as small as possible as well as satisfying the following constraints

(a) The maximum pressure of your natural gas power engine should not be higher than 10% of the fatigue limit of steel

(b) The maximum temperature of your power engine should not higher than 1000 K

(c) The fluid velocity should not be higher than 50% of the sound speed.
